This report presents the case of an 82 year old male with known dextrocardia and situs inversus totalis who developed increasing dyspnea on exertion and was diagnosed with severe aortic stenosis. Transcatheter aortic valve replacement was decided upon requiring deviation from standard techniques for patients with normal anatomy and left-sided aortic arch. We describe two technical differences required for patients with dextrocardia and right-sided aortic arch which facilitate transcatheter aortic valve replacement in this patient group...

Mitral annular calcification can pose a formidable surgical challenge in the setting of mitral valve replacement for mitral stenosis. Although there are reports of transapical valve-in-valve transcatheter mitral valve replacement in the setting of degenerated bioprosthetic mitral valve replacement, there is less experience with transcatheter mitral valve replacement for mitral annular calcification. This report describes a patient who previously received a transcatheter aortic valve replacement and then subsequently underwent a minimally invasive right thoracotomy for transcatheter mitral valve replacement with a successful result...

BACKGROUND: To assess clinical outcomes of patients with concomitant severe aortic stenosis (AS) and coronary artery disease (CAD) who underwent transcatheter aortic valve implantation (TAVI) and percutaneous coronary intervention (PCI) or surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG). METHODS: Data were extracted from the multicenter OBSERVANT study. For the purposes of the present analysis, we included only patients with established stable CAD meeting any of the following inclusion criteria: 1) TAVI patients with CAD undergoing staged PCI or TAVI and PCI in the same session; 2) SAVR patients undergoing combined SAVR and CABG in the same session...

BACKGROUND: Antithrombotic treatment regimen following transcatheter aortic valve replacement (TAVR) is not evidence-based. Apixaban, a non-vitamin K direct anticoagulant (NOAC) was shown to be superior to VKA and superior to aspirin to prevent cardioembolic stroke in non-valvular atrial fibrillation. It may have the potential to reduce TAVR-related thrombotic complications including subclinical valve thrombosis along with a better safety than the standard of care. DESIGN: ATLANTIS is a multicenter, randomized, phase IIIb, prospective, open-label, superiority study comparing standard of care (SOC Group) versus an apixaban-based strategy (Anti-Xa Group) after successful TAVR (ClinicalTrials...

BACKGROUND: The impact of frailty assessment on outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) remains unclear. Our aim was to evaluate the individual effect of each frailty test and the utility of an additive frailty index score on short- and long-term survival following TAVR. METHODS: Retrospective analysis of consecutive TAVR patients for whom a complete set of frailty tests was obtained: algorithm defined grip strength and 5-m walking tests, body mass index <20 kg/m2 , Katz activities of daily living ≤4/6, serum albumin <3...

Mitral regurgitation is the most common valvular disease and significant (moderate/severe) mitral regurgitation is found in 2.3% of the population older than 65 years. New transcatheter minimally invasive technologies are being developed to address mitral valve disease in patients deemed too high a risk for conventional open-heart surgery. There are several features of the mitral valve (saddle-shaped noncalcified annulus with irregular leaflet geometry) that make a transcatheter approach to repair or replacing the valve more challenging compared with the aortic valve...

OBJECTIVE: Chronic kidney (CKD) is associated with worse outcomes in high-surgical risk patients undergoing transcatheter aortic valve replacement (TAVR). However, it is unclear whether this relationship is apparent in lower surgical risk patients. Herein we sought to analyze existing literature to assess whether or not advanced CKD is associated with increased mortality, or a greater incidence of adverse events (specifically major stroke, bleeding and vascular complications). METHODS: We searched PubMed and EMBASE (2008-2017) for relevant studies...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become an alternative treatment to surgery in patients with severe aortic stenosis (AS). However, patients with Bicuspid aortic stenosis (BiAV) are usually excluded from major TAVR studies. The aim of this study is to reexamine the current evidence of TAVR in patients with severe AS and BiAV comparing to tricuspid aortic valve (TriAV). METHOD: Databases were systematically searched for relevant articles according to the following criteria...

A 77 year old male underwent elective bioprosthetic aortic valve replacement (23mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnoea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak / mean gradients 49 / 22 mmHg respectively)...

BACKGROUND: Stroke is a serious complication of both transcatheter aortic valve replacement (TAVR) and carotid artery disease (CD). The implications of CD in patients undergoing TAVR are unclear. METHODS AND RESULTS: The Society of Thoracic Surgeons and American College of Cardiology Transcatheter Valve Therapies Registry, consisting of data from consecutive US TAVR cases during the years 2013 to 2015, was linked to Medicare claims data to ascertain 30-day and 1-year cumulative incidence rates of stroke and all-cause mortality...

Transcatheter aortic valve replacement is now the standard of care for severe symptomatic aortic stenosis patients who are at high-surgical risk. Percutaneous approach without a surgical cut down has been increasingly adapted by some centers in USA. Percutaneous approach seems to be associated with shorter hospital stay, similar short and late vascular complications, less disabling stroke, similar mortality as well as significantly less hospital cost. However, this technique also requires operators to be able to manage any vascular complications using advanced endovascular interventions to achieve complete hemostasis...

Transcatheter aortic valve implantation (TAVI) has become an established treatment option for aortic valve stenosis in patients with a high risk for conventional surgical valve replacement. A well-known complication is the development of conduction abnormalities. In the case of a new third degree atrio-ventricular block the complication can be life-threatening and permanent pacing is needed. Often these patients have a venous sheath placed in the jugular vein for the perioperative period. We report a case of inadvertent dislodgement of a permanent pacemaker lead after removal of a preoperatively placed venous sheath in a TAVI patient...

Transcatheter aortic valve replacement has been recently approved for patients who are high or intermediate risk for surgical aortic valve replacement. The procedure is associated with several known complications including coronary related complications. Coronary obstruction is rare but disastrous complication, and it is associated with a high mortality rate. Coronary protection technique has emerged as a preemptive technique to avoid this complication. We present a case of successful coronary protection during TAVR in severely calcified left cusp in patient with short and low left ostium...

BACKGROUND: Patients with severe aortic stenosis (AS) are subjected to left ventricular hypertrophy (LVH) with increasing morbidity and mortality. Transcatheter aortic valve replacement (TAVR) induces reverse left ventricular remodeling which can be monitored by cardiovascular magnetic resonance (CMR). CMR is able to analyze myocardial tissue properties by magnetic relaxation times (parametric CMR). The objective of this study was to study myocardial T2 relaxation in reverse ventricular remodeling after TAVR...

BACKGROUND: N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) levels correlate with higher peri-procedural mortality after transcatheter aortic valve replacement (TAVR). The long-term prognostic value of NT-proBNP within the first days after TAVR, however, remains unclear. This study examined early changes in NT-proBNP prior to and within 6 days after TAVR, the diagnostic value of this biomarker regarding aortic regurgitation (AR), and its prognostic value regarding one-year mortality...

Women undergoing cardiac catheterization, percutaneous coronary intervention, transcatheter aortic valve replacement, and other structural heart interventions have a significantly higher risk of vascular complications and bleeding than men, leading to significant morbidity and mortality. This review highlights the importance of recognizing female sex as a specific and independent risk factor, and focuses on mechanisms of increased risk and strategies to minimize that risk. Smaller caliber peripheral vessels, low body weight, variations in platelet reactivity, and inappropriate dosing of anticoagulant and antiplatelet agents are the currently identified mechanisms for elevated bleeding and vascular complication risk in women...

BACKGROUND: Nutritional condition is one marker of patients' frailty. The Geriatric Nutritional Risk Index (GNRI) is a well-known marker of nutritional status. This study sought to assess the clinical outcomes of GNRI after transcatheter aortic valve replacement (TAVR). METHODS: We evaluated the GNRI value of 1,613 patients who underwent TAVR using data from a Japanese multicenter registry. According to baseline GNRI, patients were classified into 3 groups: GNRI ≥92 (n = 1,085; 67...

Underexpansion of an aortic bioprosthetic valve is common after transcatheter aortic valve replacement (TAVR). Significant discrepancy between invasive hemodynamic gradients and echocardiographic Doppler gradients in an underexpanded bioprosthesis can be attributed to pressure recovery phenomenon. This case emphasizes the importance of echocardiographic guidance in implantation and assessment of bioprosthetic valve during TAVR.

It is unknown if transcatheter aortic valve implantation (TAVI) is a safe alternative to surgical aortic valve replacement (SAVR) in patients <65 years old. Data from the National Inpatient Sample database were utilized. Patients from 2011 to 2015, ages 18 to 64 years old (inclusive) who underwent TAVI and SAVR were included. Patients who underwent SAVR and who also received a concomitant nonaortic valve surgery were excluded. A propensity score analysis was used. A total of 18,970 (528 TAVI and 18,442 SAVR) patients were identified...
